java - How do I break multiple foreach loops?

I have four foreach loops that iterate through the collections and
based on a condition do something.

Here is the
code that I am writing
now:

boolean breakFlag =
            false;
String valueFromObj2 = null;
String valueFromObj4 =
            null;
for(Object1 object1: objects){
 for(Object2 object2:
            object1){

 // I get some value from object2

            valueFromObj2 = object2.getSomeValue();
 for(Object3 object3 :
            object2){
 for(Object4 object4: object3){
 // Finally I get some
            value from Object4.
 valueFromObj4 = object4.getSomeValue();
 //
            Compare with valueFromObj2 to decide either to break all the foreach loop

            breakFlag = compareTwoVariable(valueFromObj2, valueFromObj4 );

            if(breakFlag){break;}
 } // fourth loop ends here


            if(breakFlag){break;}
 } // third loop ends here

            if(breakFlag){break;}
 } // second loop ends here

            if(breakFlag){break;}
} // first loop ends
            here

The main object
(objects in the code) comes from a third-party provider SDK, so I cannot change anything
on that portion. I want to ask the Stack Overflow community if there is a better
approach to break all the four foreach loops. Or if there is any other way to refactor
this code to make it more readable and maintainable.

Use a label on the outermost loop,
and include this label in the break statement when you want to
jump out of all the loops. In the example below, I've modified your code to use the
label
OUTERMOST:

String
            valueFromObj2 = null;
String valueFromObj4 = null;
OUTERMOST:
            for(Object1 object1: objects){
 for(Object2 object2: object1){
 //I
            get some value from object2
 valueFromObj2 =
            object2.getSomeValue();
 for(Object3 object3 : object2){

            for(Object4 object4: object3){

 //Finally I get some value from
            Object4.
 valueFromObj4 = object4.getSomeValue();
 //Compare with
            valueFromObj2 to decide either to break all the foreach loop
 if(
            compareTwoVariable(valueFromObj2, valueFromObj4 )) {
 break
            OUTERMOST;
 }
 }//fourth loop ends here
 }//third loop
            ends here
 }//second loop ends here
}//first loop ends
